The Space Shuttle food truck is absolutely out of this world, if for no other reason than its unusual history. The food truck, which is for sale on eBay, is actually a refurbished DC3 airplane built in 1976 that's been mounted on a bus frame. The truck's airplane components have allegedly been used in both World War II and Cuban hijacking.
This is just another cool way food trucks have been getting creative with old parts. The Morris Grilled Cheese Truck, for example, serves grilled cheese from a police van.
